Enterobacter

a genus of straight gram-negative rods, lactose-fermenting bacteria of the tribe Klebsielleae of the family Enterobacteriaceae. Found chiefly in the environment in water and soil but are common invaders of tissues in contaminated wounds of animals and in opportunistic infections such as cystitis and pyelonephritis in cattle. E. aerogenes (syn. Klebsiella mobilis) is occasionally a cause of bovine mastitis, uterine infections in mares and the mastitis-metritis-agalactia syndrome in sows.
